Fabrication method of high-conductivity cable

Abstract

A fabrication method of a high-conductivity cable belongs to the field of cable production and is used for solving the problems that a cable fabricated by an existing production method of a high-conductivity cable is not uniform in conductive medium and not good in conductive effect. The method comprises the steps of S1, taking a metal conductor as a raw material; S2, allowing the conductor to pass through a magnetron sputtering machine to form a graphene film, wherein the conductor automatically rotates to pass through the magnetron sputtering machine, the magnetron sputtering machine takes the graphene as a target material and is provided with a grounding line, and the grounding line is connected with the conductor through a carbon brush; S3, allowing the conductor to pass through an extruding machine to form an insulation layer outside the graphene film; S4, enabling the conductor after extrusion to pass through a cooling water groove; and winding a line. By the fabrication method, the graphene film can be uniformly formed on a surface of the conductor, and the conductor medium is uniform.

Description

technical field [0001] The invention relates to the field of cable production, in particular to a method for preparing a high-conductivity cable. Background technique [0002] At present, the conductive cores of wires and cables are usually copper or aluminum, which are generally made into conductive cores through metal smelting, rolling and stretching. The performance of the conductive core is usually improved through subsequent processes, such as electroplating tin and nickel on the surface of the conductive core to improve its oxidation resistance, mechanical properties and corrosion resistance, respectively. The metal introduced in the subsequent process usually has poor conductivity, which has an adverse effect on the performance of the wire and cable, and the increase in the number of layers will not only increase the complexity of the process, but also increase the weight and cost of the wire and cable. [0003] Graphene has high strength, excellent biocompatibility,...

AI Technical Summary

Problems solved by technology

[0005] The disadvantages of Patent Document 1 are: 1. The cable core is a copper alloy; 2. Although the copper-graphene multiphase coating has higher conductivity than other tin-plating and nickel-plating anti-oxidation methods, the conductivity is still limited

[0007] The shortcoming of patent document 2 is: adopt the mode of mechanical exfoliation to obtain graphene flakes, then overlap the copper sheet with graphene flakes for forging, wherein graphene is mixed in copper, but the distribution of graphene is inhomogeneous, and its line The conductivity of the cable is inconsistent, and there will be breakpoints. When a certain breakpoint occurs, high conductivity cannot be achieved

[0009] The disadvantage of Patent Document 3 is that, by coating graphene on the base film, and then overlapping multi-layer sheet-like base films, and winding them into electric wires, there is the same design idea between Patent Document 2 and Patent Document 3, and the production The conductive medium of the wire is not uniform, and the conductivity is unstable
